Magnetic switch ke sesebelisoa sa motlakase se feto-fetohang se sebetsang ka ho arabela matla a khoheli. Ho tloha Hall Effect ho ea ho li-switches tsa lehlaka, hlahloba mesebetsi ea tsona, mefuta le lits'ebetso tse fapaneng.

Phetoho ea Magnetic ke Eng?

Phetoho ea makenete ke sesebelisoa sa motlakase se sebetsang ka ho arabela boteng ba matla a khoheli. E sebetsa ka ho koala kapa ho bula likhokahano tsa eona ho latela matla a matla a khoheli. Ka ho khetheha, switch e lula e koetsoe (e butsoe) ha e pepesehetse matla a khoheli a matla 'me e bula (e tima) hang ha tšimo e tlosoa.

Phetoho ea Magnetic e sebetsa Joang?

Phetoho ea makenete e sebetsa ka ho sebelisana ha likarolo tse peli tsa bohlokoa: mochini oa makenete le switch ea lehlaka. Magnetic actuator ke makenete e nyane e kentsoeng ka har'a sebaka se sirelelitsoeng, athe switch ea lehlaka e na le tube ea khalase e nang le likhokahano tse peli tsa tšepe. Ha magnetic actuator e atamela haufi le switch ea lehlaka, matla a eona a khoheli a susumetsa likhokahano tsa tšepe, e leng se etsang hore li hokahane le ho koala potoloho kapa li arohane le ho e bula.

Molao-motheo oa mantlha o kenyelletsa ho hlasimolla le ho felloa ke matla ha khoele ea makenete ea motlakase. Ha motlakase o phalla ka khoele, o hlahisa matla a khoheli a hohelang limakenete tse haufi kapa likarolo tsa tšepe. Hang ha motlakase o ema, matla a khoheli aa oa, a ntša matla a bolokiloeng. Ts'ebetso ena e tšoana le ho otlolla le ho lokolla sehlopha sa rabara, moo matla a tsoang kapele.

Li-switch tsa makenete li na le maemo a fapaneng haholo ebile li hanana le maemo a tikoloho joalo ka metsi, oli, leqhoa, lerōle le tse ling. Mehlala e tloaelehileng e kenyelletsa li-switch tsa electromechanical, li-sensor tsa Hall, le li-switches tsa lehlaka. Ho tšoarella ha bona le ho feto-fetoha ha maemo ho etsa hore ba tšoanelehe bakeng sa lits'ebetso tse fapaneng maemong a indasteri le a malapa.

Mefuta ea Liphetoho tsa Magnetic

Li-switches tsa Magnetic li tla ka mefuta e fapaneng, e 'ngoe le e' ngoe e etselitsoe lits'ebetso le melaoana ea ts'ebetso. Ka tlase ke mefuta ea mantlha ea li-switches tsa magnetic:

Holo Effect Swichis

Li-switch tsa Hall Effect ke lisebelisoa tsa semiconductor tse sebetsang ntle le ho kopana le mochini, li li etsang hore li tšoarelle nako e telele ebile li hanana le ts'ebetso ea mochini kapa ho ts'oha. Li-switch tsena hangata li sebelisoa e le li-switches tse fokolang lits'ebetsong tse joalo ka lisistimi tsa lifti, lisebelisoa tsa boiketsetso tsa feme le likoloi.

Li-switch tsa Hall Effect li fana ka maemo a feto-fetohang moralong ka likhetho tse kang Unipolar (ho bona palo e le 'ngoe ea makenete) kapa Omnipolar (ho lemoha lipalo tse ka Leboea le Boroa). Kutlo ea bona ea matla a khoheli e ipapisitse le matla a motlakase a sebelisitsoeng le mofuta oa matla a khoheli a hlahisoang, e ba lumellang hore ba lokisetsoe litlhoko tse fapaneng tsa ts'ebeliso.

Reed Switches

Li-switches tsa lehlaka li na le kutloelo-bohloko haholo ho matla a khoheli 'me li tsebahala ka ho boloka litšenyehelo le ho ikamahanya le maemo. Li-switches tsena li sebelisoa haholo lits'ebetsong tse haufi kapa tse fokotsang, ho kenyeletsoa mehala ea cellular, mamati a lisebelisoa tsa lapeng, lialamo tsa ts'ireletso, mechini e boima le mamati a likoloi.

Li-switches tsa lehlaka li ka etsoa ho latela lintlha tse kang boholo ba lehlaka, maemo a tikoloho, le matla a matla a khoheli a sebelisitsoeng. Ts'ebetso ea bona e lekantsoe ho latela matla a magneto motive force (AT - Ampere-Turns), e etsang hore li feto-fetohe bakeng sa litlhoko tse fapaneng tsa ts'ebetso.

Liphetoho tsa Triac kapa Transistor

Li-switches tsa Triac le Transistor li rarahane ho feta ka lebaka la potoloho ea tsona e eketsehileng. Li sebelisoa haholo-holo bakeng sa taolo ea matla le lits'ebetso tsa switching ho li-voltage tsa AC (Triac) kapa DC (Transistor). Li-switch tsena li matla 'me li loketse lits'ebetso tsa morao-rao kapa tse boima, joalo ka lienjineri tse laolang, li-relay kapa meroalo e kenang.

Bokhoni ba bona ba ho jara hona joale bo ka ntlafatsoa ka ho li kopanya le li-switches tsa Hall Effect kapa Reed, e leng se etsang hore e be tse loketseng bakeng sa maemo a boima a indasteri moo ho ts'epahalang le matla a leng bohlokoa.

Li-switch tsa makenete li sebelisoa hokae?

Li-switches tsa makeneteli sebelisoa haholo liindasteri le lits'ebetso tse fapaneng ka lebaka la ho feto-fetoha ha tsona, ho ts'epahala, le bokhoni ba ho sebetsa ntle le ho ama 'mele. Ka tlase ke tse ling tsa libaka tsa mantlha moo li-switches tsa makenete li sebelisoang:

• Lisebelisoa tsa Koloi: E sebelisoa ho li-switches tsa mabone a marang-rang, li-sensor tsa mamati, ho lemoha boemo ba gear, ho lemoha boemo ba throttle, le ho hlahloba lebelo la mabili.
• Industrial Automation: E hiriloe bakeng sa taolo ea mabanta a conveyor, ho lemoha boemo ba menyako le heke, tlhokomelo ea lisebelisoa, mochini oa tlhahiso ea lihlahisoa, le ho lemoha boemo ba valve.
• Consumer Electronics: E fumaneha ka har'a lilaptop le li-smartphones bakeng sa ho bona sekoaelo le sekoaelo, likarolo tse baballang matla, boemo ba lense ea khamera, le ho lemoha haufi le lisebelisoa tse bohlale.
• Tshireletso Systems: E sebelisoa ka lialamo ho lemoha ho buleha kapa ho koaloa ha mamati le lifensetere.
• Thepa ea Bongaka: E sebelisoa ka har'a likoahelo tsa lisebelisoa tsa bongaka, lisebelisoa tsa ho beha leihlo bakuli, lits'ebetso tsa ts'ireletso tsa mochini oa MRI, le ho lemoha lisebelisoa tsa ho buoa.
• Matla a Tsosolositsoeng: E ​​sebelisoa ka har'a li-turbine tsa moea le liphanele tsa letsatsi bakeng sa ho lekola ts'ebetso le ho ntlafatsa.
• Likhokahano tsa mehala: E kopantsoe le lisebelisoa bakeng sa ho kenya skrineng ka boiketsetso, ho lemoha lisebelisoa, le likarolo tse baballang matla.
• Lisebelisoa tsa Lehae: E fumanoa mecheng e hlatsoang le lihatsetsing bakeng sa taolo ea phallo ea metsi le mekhoa ea mamati.
• Mechini e boima: E sebelisetsoa ho lemoha maemo le ho laola lisebelisoa tsa indasteri.
• Tikoloho e Khethehileng: E ​​loketse maemo a kotsi kapa a kantle ka lebaka la ho hanyetsa lerole, mongobo, oli le mocheso o feteletseng.
